COMBINED GENERATOR AND BURNER.

Specification of Letters Patent.

Patented May 22, 1917.

Application filed December 16, 1913. Serial No. 807,042.

To this end the invention consists in the features of construction, combination, and

arrangement of parts hereinafter described and claimed.

In the accompanying drawings forming part of this specification,

Figure 1 is a plan view of a generator and burner apparatus containing my features of invention; I

Fig.2 is an elevation of the generator 5 part of the invention;

Fig. 3 is a longitudinal section of one of the generating retorts;

Fig. 4 is a section on line 03% of Fig. 5; and

Fig. 5 is a section on line yy of Fig. 4. Referring to the drawings, A represents the central chamber of the main burner. The central chamber A supports a plurality of branch conduits 2 carrying burners 3. A gas inlet tube 4 is attached to one side of the chamber A. For the purpose of supplying the burners with the combustible gases, I employ reservoirs B and O, the reservoir B being adapted to contain water, and the reservoir C a heavy liquid hydro-carbon as kerosene. Compressed air is placed upon the fluids in the reservoirs, through the inlet pipes 5, from a source of supply not shown. The reservoirs are provided with outlet pipes 6 and 7 controlled by suitable valves 8. The water pipe 6 leads to a pipe 9 supported centrally within the retort 10, said pipe Qterminating short of the forward end of the retort. The liquid hydrocarbon pipe 7 leads to a, pipe similarly pos1- tioned within the retort 11. The retorts 10 and 11 are supported by arms 12 and 13 extending upwardly from a pipe 4. The arm 13 supporting the retort 11 is connected w th the pipe 4 forward of the connection w1th the arm 12. A conduit 14 leads from the retort 10 above the pipe 9 downwardly through the arm 12 to the pipe .4 as shown in Fig. 5. Similarly a conduit 15 extends from the retort 11 tothe pipe 4 forward of the conduit 14. The pipe 4 forward of the conduits 14 and 15 is'formed with an air recelving opening 16 for the purpose hereinafter set forth. Having screw threaded support within the pipe 4 on the outer side of the air opening 16 is a cylindrical valve 17, the inner end 18 of the valve being tapered and fitted to a jet opening 19. The cylindrical valve carries an actuating handle 20 and is formed with port openings 21 to allow communication between the conduit 14 and interior of said valve. Having screw threaded support within the cylindrical valve 17 is a valve 22, the valve 22 being formed with a pointed end 23 fitted within the outlet opening 24 of the inclosing valve. The valve 20 is circumferentially cut away lnside the inclosing valve as shown in Fig. 5 and carries at its outer end an actuating handle 25.

For the purpose of furnishing sub-flames to heat the retorts and the gas supply tube 4, I provide a sub-flame pipe 26 leading outwardly from the burner chamber intermediate of the retorts 10 and 11, the outer end of the sub-flame pipe being preferably supported as by a bracket 27. The sub-flame pipe is formed with outwardly directed subflame burners 28, directed as shown in Fig. 2 toward the retorts, being also provided with downwardly extending sub-flame burners 29. As indicated in Fig. 2 the sub-flames from the burners 28 will directly heat the retorts, while the sub-flames from the burners 29 will be directed against the pipe 4 to heat the same and the contained valves and the jet openings shown in Fig. 5.

In operation, water from the reservoir B and liquid hydro-carbon from the reservoir 0 will be supplied to the retort-s by reason of the air pressure in the reservoirs. The generator having been preliminarily heated by external means, as a torch, will continue generation in the following manner: The gasified liquid hydro-carbon will pass around the inner end of the cylindrical valve 17 and through the jet opening 19, the steam formed from the water passing through the jet opening in the end of the cylindrical valve and into the center of the stream of hydrocarbon gas. The steam passing into the center of the stream of hydro-carbon gas thoroughly commingles With it and the commingled steam and gas takes up the air through the opening 16 and pipe 4 and passes.into the chamber- A to supply the burners 3. A portion of the gas in the chamber A passes back through the pipe 26 to supply the sub-flame jets 28 and 29. The

sub-flames from the jets 28 being directed against the sides of the retorts 10 and 11 Will heat the contained Water and liquid hydro-carbon to vaporize the same, the steam from the ater and the gas from the hydrocarbon passing from'the retorts to the supply tube 4. The sub-flames from the jets 29 Will, as Wlll be evident, heat the tubular valve and heat around the jet orifice 19, keeping the gas and steam in proper condition for passing to the burners.

I claim as myinvention:

1. An oil burner comprising oil and Water reservoirs, conduits connected thereto, retorts forming parts of said conduits, a valve casing connected to the oil conduit, a tubular valve Within the casing having communication With the Water conduit, a controlling copies of this patent may be obtained for connecting said retorts With said mixing conduit, a main burner chamber, said mixing conduit being formed with a jet opening directed into said burner chamber, valve mechanism inclosed Within said mixing conduit for regulating the passage of gas and water vapor therethrough, and sub-flame burners fed from said main burner chamber and arranged in position to heat said retorts.

In testimony whereof I affix'my signature in presence of 'tWo Witnesses.
